Versuche nun schon seit einer Weile das [ScheduledTask Plugin](http://github.com/shopware/swag-docs-scheduled-task-plugin) ans Laufen zu bringen, bekomme aber einen&nbsp; **„No handler for message „Swag\ScheduledTaskPlugin\ScheduledTask\MyTask“.“** Fehler, sobald das Plugin aktiviert und der&nbsp;ScheduledTask ausgeführt wird.

Folgende Schritte wurden ausgeführt:

1. Plugin gecloned

2. Plugin-Liste refreshed

3. Plugin im Backend installiert

4. Den Admin-Worker deaktiviert

5. Den Cache geleert

6. Den Task-Runner gestartet

7. Den Message-Consumer gestartet

8. Das Plugin im Backend aktiviert

Anschließend erscheint folgende Fehlermeldung im Message-Consumer:

```

Vermutlich sitze ich schon zu lange dran und übersehe irgendwas essentielles. Aber was?

PS: die Tabelle „_dead-message_“ in der Datenbank ist leer.

PPS: es handelt sich um eine [dockware](https://dockware.io/) Umgebung mit **Shopware in der**** Version 6.3.3.0**

Any luck with this?

How did you solve?

It’s been a long time and I’m not sure if I remember correctly to be honest.

I think I had to manually delete the cache directories (located in `var/cache`). But using the ScheduledTask functionality was a pain actually and I finally decided to use another approach.
